Biological and Chemical Warfare Agent Field Detectors and Triggers


A White Paper By Proengin

Proengin has developed biological and chemical warfare agents field detectors using flame spectrophotometry. The well-known and world-wide used AP2C has proven the capacity of flame spectrophotometry to be the most reliable on the field with the lowest false-alarm rate and the simplest ease of use.

  • New developments such as the AP4C chemical detector have extended the capacity of that technology to include chemical warfare agents, such as sarin or mustard gas and toxic industrial materials in a simultaneous mode. There is no limitation to the number of gases detected by the AP4C.
  • The biological detector MAB has the unique capacity of detecting and categorizing biological particles with a proven extremely low false-alarm rate and the unique capacity to discriminate dangerous or suspicious biological particles such as anthrax spores from natural background.

The AP4C

The AP4C handheld chemical detector has extended the range of chemicals that can be detected by Proengin chemical detectors. All dangerous compounds containing sulphur, phosphorus, arsenic, and / or chemical liaisons can be detected simultaneously. Of course, as for the AP2C, the AP4C has the capacity to work in very severe environmental conditions and the measurements are unaffected by high humidity levels or by the presence of other organic chemical compounds such as paint. Moreover the AP4C can run in highly explosive areas.

The AP4C technology allows the simultaneous detection of an unlimited number of gases and the identification of the chemical elements that constitute these chemicals. It is therefore possible to detect impure agents or chemicals manufactured by terrorists that would not fit into traditional libraries of other detectors.

Moreover, the AP4C will detect new agents that will be developed in the future without needing an upgrade.

The response time is among the shortest on the market, but what makes the AP4C unique is the recovery time after a positive detection. Where other detectors may take long minutes or hours after a positive detection or pollution by chemicals, AP4C will be ready in seconds, whatever the level of contamination.
The AP4C is therefore the chemical detector that has the highest level of availability of the field. Test reports of independent laboratories are available on request.


Complexity, false alarms and high power consumption are the main reasons why it is difficult to deploy biological detectors on a battlefield. The MAB biological detector has circumvented all those problems by using the same technology as the AP4C.

Highly-ruggedized, very simple to use on the field and with extremely-low power consumption (15W), the MAB also has unique features in terms of biological detection. No other field detector is able to detect tiny biological particles, to categorize them by chemical composition, to discriminate background particles from suspicious particles, and even to differentiate between those suspicious particles. All this will run the same way in a cloud of smoke or in an atmosphere polluted by high-levels of diesel exhaust. Test reports of independent laboratories clearly show the superiority of the MAB.
